The Xbox 360 Mass Effect 3 Multiplay servers will be offline Tuesday August 28 starting at 10am GMT. The downtime will last approximately 1 hour.
This maintenance only affects Xbox servers. PC and PS3 servers will not be impacted.
We will work to get the servers back online as soon as possible. We appreciate your patience while the maintenance is completed.
Interesting timing considering thats the usual time when new Marketplace content such as Leviathan will be available, no bigger for most UK peeps I shouldnt think
